Science Girl Dresses as a Princess to Feed the Entire Dynasty

Dressed as the crown prince of a subjugated country, she was exiled at the beginning? Lin Xiaotang, a modern social animal, died suddenly after staying up late to write a thesis. When he woke up, he saw a tyrant handing him a glass of poisoned wine. In order to survive, she backhandedly presented "National Defense and City Defense Construction and Local Methods for Preparing Saltpeter". A hard-core engineering female doctor relied on knowledge to fight her way out. Exiled to the northern border, invaded by barbarians? She led the wives of guilty ministers to start a "women's school", which taught advanced mathematics and physical chemistry. Three years later, the barbarians came to the city, but what she set up on the city's head was a trebuchet and black powder. The legendary and vicious God of War who died in battle returned from the bloody battle, only to find her giving a physics lesson to the enemy with a loudspeaker: "Do you understand ballistic parabolas? If you don't understand, I'll bomb you until you understand!" The prince looked at her, then at the messy battlefield, and silently withdrew his sword: This princess looks more like an enemy than an enemy.
